The probe annular seal space of making is fixedly mounted in described device skeleton, has fully sealed one in described probe sealing intracavity
Probe, carries out signal transmission using main cable connection between multiple described probes, is filled with solid-filling in described PU pipes
Glue.
Described stifled core is combined with described PU pipes and withholds sealing.
It is equally spaced between multiple described device skeletons and described empty skeleton.
Described main cable is arranged in the outside of described empty skeleton and described device skeleton, adjacent described empty skeleton
Main cable described between described device skeleton leaves surplus, it is to avoid main cable is stressed directly.
In order to solve above-mentioned second technical problem, the method for the assembling solid-state towed sonar linear array that the present invention is provided,
Installation step is as follows：A, empty skeleton and device skeleton are equally spaced, are mechanically fixed with Kev drawstring；B, Kev drawstring with it is stifled
Core is fixedly connected；C, the outside that main cable is fixed on sky skeleton and device skeleton, and needing the position of connection probe
Carry out choosing fibre；D, probe is sealed in probe sealing intracavity, the signal optical fibre that reserves of popping one's head in chooses fine connection with main cable；E, will visit
Head annular seal space is fixed in device skeleton；F, the empty skeleton of naked battle array, device skeleton and main cable are put into PU pipe, the stifled core at two ends
With PU pipe thread means of press seals；G, by blocking up the glue filling opening of core end face to filling liquid colloid inside PU pipes, filling finishes seal plug core
Encapsulating mouth, after colloid is solidified into solid-filling glue, formed solid-state array；H, some strip arrays are attached to form solid-state
Towed sonar linear array.
Using the solid-state towed sonar linear array and its assembly method of above-mentioned technical proposal, relative to oil-filled array, have
Following significant advantage：
1) flow noise is little；
2) array reliability is high；
Even if 3) array is damaged, pollution will not be produced to marine environment also.
By the way of solid colloid filling, the device such as probe is individually sealed the array using acoustic window material, it is to avoid colloid
Into its acceleration sensitivity of probe internal influence.The present invention is a kind of array of solid filler, compare liquid underfill with
Lower advantage：Flow noise is little, and array reliability is high, once array destruction will not produce the advantages such as pollution to marine environment.
In sum, the present invention is that a kind of flow noise is little, array reliability is high, array destruction will not be produced to marine environment
The solid-state towed sonar linear array of pollution.Its assembly method is simple and reliable.
